Forge Server not Accessible from browser and Nginx Config file missing

Hello, I just recently signed up for digital ocean and forge server and going through the setup. The server seems to be working fine

• I could access the ubuntu server from terminal
• I can see that the server is active and connected from forge cp
• I already set up ssh key successfully

but I could not find Nginx config file from the forge control panel. When I click on edit file on the 'apps' tab, this what i get with an empty panel. " cat: /etc/nginx/sites-available/mabinok.com: No such file or directory " so when I go onto browser with my forge server ip address, browser replies, "couldnot connect to the server". I don't even get the 404 page. Am new for this thing. Please help
